5Check Digit Verification of cas no
The CAS Registry Mumber 8005-84-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.Calculate Digit Verification of CAS Registry Number 8005-84:
(6*8)+(5*0)+(4*0)+(3*5)+(2*8)+(1*4)=83
83 % 10 = 3
So 8005-84-3 is a valid CAS Registry Number.
